COMPUTING-MEASURE.

Specification of Letters Patent. I

g Application led Hatch 25, 1911. Serial No. Bl.

To all whom it may concerm- Be it known that I, DAVID H..LAYNE, a citizen of the United States, residing at Cove, in the county of Union and State of Oregon, have invented certain new and useful Improvements Lin Computing-Measures, of which the following is a specification.

The measure which is the subject of the present invention is designed more particularlyv for use in connection with the sale of rope, and it consists in a novel construction and arrangement of parts to be hereinafter described and claimed.

Rope is usuall jobbed by the pound and retailed by the oot or moneys worth, and the present method of converting foreach transaction is always slow and ofteninaccurate, which, combined ,with the natural shrinkage of the rope, often results in elimination of the merchants profits, especially on small amounts of rope sold.

` It is the object of the present invention to provide a computing measure which is approximately correct, based on the standard Weight and measure of both manila and sisal rope adopted by manufacturers and jobbcrs, it being as nearly correct as is practical to make change. 'd

In the accompanying drawing forming a part of this s ecication, Figure 1 is a plan view of one side of the measure, and Fig. 2 is a erspective view showing one end thereoi Y Referring specifically to the drawing, the invention is in the form of a yardstick 5, the Same being constructed of wood,.metal, composition, or any other suitable material. The side of the stick shown in the drawing is provided at one of. its longitudinal -edges with inch graduations 6. `The face of the stick is divided into a plurality of spaces by lines Z extending perpendicularly between the longitudinal edges of the stick. These spaces containcolumns of numerals indicating the prices of different quantities of rope. At the foot of each space is an index or mark indicating the size of the rope to which the computations found in saidv space refer.

As shown in'the drawing, the index or mark of the first space at the left hand end of the stick is the fraction i which means that the computations in that space 'refer to rope which is one-fourth of an inch in diameter. The index or mark for thev next l space is 15g, which indicates that the computations in this space refer to rope having a diameter of ve-sixteenths of an inch. The next space is marked for inch rope,

the next space for {ginch rope, andthe last space for inch rope.

Referring now to the columns of numerals' appearing in each space, itl will be noted that they are arranged in pairs, each pair being headed -by an index character. As shown, these index characters comprise the numerals 1o, 12, 13, 14., 15, 16, 17,18,2o,22,and aathey indicating selling prices in cents. One of the members of each pair of columns is .headed FT indicating that the numerals appearing in said column represent feet. The other Vmember of each pair of columns is headed C, indicating that the numerals appeering iii that column represent different monetary values in cents. rIhe numerals indicating monetary values are arranged 0pposite the numerals re resenting quantities.

The measure is use as follows: Assuming acustomer asks for fifty feet of onehalf inch rope, if this size is selling at lifteen cents, the merchant picks out the pair of columns containing the index 15, in the space containing the index mark ,-and goes down the column of :feet until the numeral 50 is reached. In column of centsnext to the numeral 50, appears the numeral 55 which indicates that 50 feet of inch rope sells for 55 cents. Assuming that the next customer wants fifty cents Worth of inch rope, the merchant reverses the herein de-k scribed operation by first going down the column marked C until the numeral 50 is found, opposite which the numeralft appears in the column marked FT, thus indieating that fifty cents purchases 45 feet of rope. If .a merchant is selling inch rope at fifteen cents and finds that it does not bring 4enough profit, he can change to the 16, 17, or any other centcolumn to make his profit right. If'7 5 feet'of rope is wanted, the cost may be readily ascertained by adding the cost of 50 and 25 feet; if 90 feet is wanted, add the cost of 50 and 40 feet, and so on. If200 feet is wanted, multiply the cost of 50 feet by 4.

In order to guide the rope alon the stick WhileV being measured, one end o the -stick has a tongue Son which is mounted a ring l.9 having anenlargement 10 which is provided with a slot 11 to receive the tongue. The ring extends at a right angle to the face of .the stick when it is in position for use, it being held inplace by slipping the esV width than held in proper position at the end of the stick and is 'prevented from slipping across the same. The tongue is provided with a erforation 12 in order that the stick may tongue into e hung up on a nail c@ other support when v 1n presence of two wltnesses.

not in use. A

The drawing only shows one side of the stick, and it- 1s to be understood that the other side of the stick may also contain computations for other sizes ror rope.

I claim: v

A. measuring stick having a tongue projecting from one end thereof and of less Width than the stick, whereby a shoulder is formed on the stick, and a guide ring hav-` ing an enlargement provided with a slot to receive the tongue, said ring abutting against the shoulder.

In testimony whereof I affix my signature DAVID H. LAYNE. Witnesses:
